LA 8 T SPECIFICATION forming part of Letters Patent No. 639,034, dated December 12, 1899.

Application filed January 24, 1898. Serial No. 667,711. (No model.)

To all whom it may concern:

Be it known that we, JOHN HARPER and ABRAHAM T. HARPER, citizens of the United States of America, residing at Portland, in the county of Cu mberland and State of Maine, have invented certain new and useful Improvements in Lasts; and we do hereby declare the following to be a full, clean and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in lasts, and more particularly to hinged lasts. As at present constructed it is necessary in all cases, so far as we are aware, to divide the last transversely before the holes are made in the heel and toe parts, respectively, in which the unions are to be inserted. The location of these holes after the last is divided, in order that they may register, is a matter of very accurate measurement. Especially is this true on account of the irregular shape of the last.

The purpose of this invention is to obviate this objection, and this we do by boring the holes before the last is divided in the manner hereinafter described, and shown in the drawings herewith accompanying and making a part of this application.

In said drawings, Figure 1 is a side elevation of a portion of a last, showing one method of boring the holes for the insertion of the unions. Fig. 2 is a side elevation of a portion of a last, showing a different method of boring the holes for the insertion of the unions. Fig. 3 is a horizontal sectional view of Fig. 1, and Fig. 4 is a substantially horizontal sectional View of Fig. 2.

Same letters and figures of reference refer to like parts in Figs. 1 and 3 and in Figs. 2 and 4, respectively.

In Fig. 1 the holes for the insertion of the unions are made by a single bore entering the heel part back of the proposed line of division and extending diagonally and forwardly through the heel part and into the fore part.

In Figs. 2 and I the holes are bored diagonally, as before, beginning at the point of proposed division and extending diagonally into the fore part and into the heel part, re-

. across the last.

spectively. In both cases the holes may be bored before the last is divided.

In Figs. 1 and 3, A and 13 represent the fore part and heel part, respectively, of a last; 0, the holes extending diagonally across the line of division, and D the unions inserted in said holes, the holes being located at the bottom of the space F, formed by the removal of a portion of the last to permit the heel part to be turned upwardly and forwardly.

In Figs. 2 and i, 1 and 2 represent the fore and heel parts, respectively, of a last; 3, the holes extending from the point of the proposed line of division, and i the unions inserted in said holes, the holes being located at the bottom of the space 5, formed by the removal of a portion of the last to permit the heel part to turn upwardly and forwardly. In each case the holes extend diagonally The ends of the unions may be secured in their holes in any convenient manneras, for example, by pegs G or pegs 6, respectively.

The advantages of our improved construction are great saving in the time required to locate the holes for the ends of the union, absolutely perfect register therefor, and better and cheaper lasts.

Having thus described our invention and its use, we claim- In a transversely-divided hinged last, the combination of a fore part and aheel part with a pair of hinging devices, one near one side and the other near the other side of the last, the fore part and heel part being formed with spaces between their opposed walls, above the hinge devices, and with reciprocal bearing surfaces below the hinge devices, each of said hinge devices being anchored in the heel part and extending into the fore part at an angle to the longitudinal axis of the last and anchored in the fore part.

In testimony whereof we affix our signatures, in presence of two Witnesses, this 19th day of January, 1898.
